Vitamins B1 (Thiamine) and B2 (Riboflavin): Energy and Cellular Health
Thiamine and riboflavin convert nutrients into energy and support neurological function and cell growth.
Deficiencies are uncommon due to food fortification but may occur in heavy alcohol consumers, causing confusion and mouth fissures.

- Vomiting and bowel irregularities
- Fatigue and mental disturbances including hallucinations
Vitamin B3 Food Sources

Vitamin B9 (Folate): Essential for Growth and Development
Folate naturally occurs in foods, while folic acid is the synthetic form added to fortified products.
Since mandatory fortification began in 1998, folate deficiency has declined, but symptoms can include:
- Megaloblastic anemia
- Fatigue and difficulty concentrating
- Irritability and headaches
